REMOVAL
WARNING: To prevent glass splinters from entering the eyes or cutting hands, wear safety glasses and heavy gloves when cutting the glass from the vehicle. Failure to follow these instructions may result in personal injury.
1. Remove the headliner.
2. NOTE:
- Lubricate the urethane adhesive with water to aid the special tool when cutting.
- Locating tabs need to be cut through in order to remove the rear quarter window glass. The new quarter window glass will be equipped with new locating tabs.
Using the special tool, cut the urethane adhesive from the quarter window glass starting at the top center and working toward the bottom corners and remove the rear quarter window glass.
3. Using a soft brush or vacuum, remove any foreign material or dirt from the pinch weld.
INSTALLATION
CAUTION: After installing the urethane installed glass, the vehicle should not be driven until the urethane adhesive has cured. The curing time at temperatures above 13°C (55°F) and relative humidity above 50% is 12-24 hours. (Refer to the Essex drive away chart for the cure times as temperatures and humidity vary.) Inadequate curing of the urethane adhesive will adversely affect the strength of the urethane bond.
1. Dry fit the quarter window glass, making alignment marks with tape or non-staining grease pencil.
2. CAUTION: Do not scratch the pinch weld area.
Trim the remaining urethane adhesive on the pinch weld to within the specification.
- The existing urethane adhesive surface should be smooth and free of cuts and contamination.
3. CAUTION: Use caution when applying Urethane Metal Primer Essex U-413. Apply a light amount of primer. Too much primer will run and damage the painted surface.
Use a wool applicator to apply Urethane Medal Primer Essex U-413 meeting Ford specification WSB-M2G234-C to any exposed metal on the pinch weld. Allow 6 to 10 minutes to dry.
4. Clean the inside of the quarter glass surface with alcohol-free cleaner, making sure the ceramic coated area is clean.
5. NOTE: Wipe off the glass prep immediately after each application because it flash dries.
Apply Urethane Glass Prep Essex U-401 meeting Ford specification WSB-M5B280-C twice around the glass surface to urethaned.
6. Apply Glass Primer Essex U-402 meeting Ford specification WSB-M2G314-B to the same area that was prepped in the previous step. Allow five minutes to dry.
7. Cut the urethane adhesive applicator tip to specification.
8. NOTE: Use caution when applying urethane adhesive. Apply to the outside edges of locating tabs on the glass surface.
Apply a bead of Urethane Adhesive Essex 400-HV or Essex U-216, which meets Ford specification WSB-M2G316-B. Start at the bottom and work around to the sides of the quarter window glass.
9. Install the quarter window glass, aligning it to the marks previously made.
10. After the quarter window glass is set, check for water leaks and add urethane adhesive where needed.
11. If necessary, remove excess urethane adhesive from the outside surface of the quarter window glass.
12. Install the headliner.
